Bought a used BG w/laser recently. (Seemed to make sense as I had a small stash of .390 ammo). Anyway, all was fine, took it to the range and it ran well. Cleaned it, and have carried it for several months. Figured I would take it to the range again. All of a sudden, I can't "fully" rack the slide. It won't go the last 1/8" that allows you to engage the slide stop or use the disassembly lever. What the heck could it be? Recoil spring kinked? Jeez, I don't want to send it to the factory, that would be a monster pain. Any suggestions, or am I doomed?
